This issue contains topics on foodborne and waterborne transmission of cryptosporidiosis; Anisakiasis and Anisakis; plasma histidine concentrations as a specific biomarker for intestinal mucosal damage in calves with cryptosporidiosis; effect of recumbency and body condition score on open-lung...

A 2-y-old Brahman bull was presented with progressive hindlimb ataxia and paraparesis that led to recumbency. Postmortem examination revealed scattered pinpoint, red-brown foci within the brainstem and gray matter of the spinal cord, and a larger lesion within the spinal cord at the level of T13....

In northern climates, gastrointestinal nematodes diminish cattle weight gains by roughly 0.05-0.15...

Control of gastrointestinal nematodes (GIN) can have both economic and health benefits for cattle operations in the southern United States.

Fading elk syndrome, or chronic ill-thrift of elk, is a disease associated with abomasal parasitism with Ostertagia species, of which elk appear to be particularly susceptible. While this syndrome has been extensively reported to affect wapiti-type red deer hybrids farmed in New Zealand since the...

Gastrointestinal nematode (GIN) infections in cattle cause appetite suppression which leads to poor feed conversion, reduced weight gain and reduced milk production. Overuse and exclusive reliance on anthelmintic drugs has resulted in widespread resistance in many parasitic nematode species...
